Simulating 2-D pipe flow over a backward facing step and assessing the effect of mesh grading using the icoFoam solver in OpenFOAM

Objective: INTRODUCTION: In this project, we will be solving the incompressible laminar Navier-Stokes equation using the icoFoam solver for a pipe flow over a backward facing step. The results for different near-wall mesh grading factors are compared. Different inlet velocities are also used to compare the separation and reattachment…
